3/8"-16 Conquest Heavy Hex Nut, A563 Grade A – Hot Dip Galvanized

The 3/8"-16 Conquest Heavy Hex Nut is a corrosion-resistant carbon steel fastener with hot dip galvanized finish, built to ASTM A563 Grade A specs. It’s a reliable, general-purpose nut for use in framing, fencing, or mechanical projects exposed to weather or humidity.

Weather-Resistant Nut for Framing and Outdoor Fastening

With its coarse 16 TPI thread and oversized hex body, this nut is ideal for use with galvanized A307 or Grade 55 threaded rods. The larger profile improves tool engagement and load distribution—making it a go-to choice for structural hardware and exterior connections.

Key Features

  • Material: Carbon steel with corrosion-resistant hot dip galvanized finish.
  • Thread Type/TPI: 16 TPI coarse thread for easy threading and firm grip.
  • Heavy Hex Design: Improves torque control and bearing surface.
  • Finish: Hot dip galvanized for extended service life in outdoor conditions.
  • Standard Compliance: ASTM A563 Grade A approved.

Applications

  • Metal framing and outdoor structures
  • Pole line and bracket mounting
  • Fencing and farm equipment assembly
  • Utility installations in exposed locations
  • General construction and repair work

Installation Tips

  • Use with 3/8"-16 galvanized bolts or rod for best fit.
  • Torque using hex-compatible sockets or impact tools.
  • Remove galvanizing flakes before threading for smooth assembly.

Quality, delivery, prices excellent

I recently ordered some nuts, bolts, washers, screws, and ties for a pergola build. Their selection was great, product descriptions thorough, and delivery, and price excellent compared to other online stores and big-box stores. Will be buying from them in the future.
